1 Claim, 26 Drawing Figures PATENTED AUG 14 I973 SHEET 1 0F 5 PATENTEDMIB I4 1975 SHEEI 3 OF 5 STRUCTURE FOR THE ASSEMBLY OF FIXTURES FORDOORS, WINDOWS AND THE LIKE This invention relates to an improvement inmetal structures, particularly of the type used in buildingconsturctions for the preparation of fixtures and the like.

It is well known that there exist in the building field various types ofmetallic structures used for the preparation of fixtures: each fixtureinvolves, however, the use of a determined type of structure, thusgiving rise in the practical industrial application to inconveniences onaccount of the structural differences occurring between the severalelements which,.when used in one single unit, require painstakingadjustment. This fact interferes with the achievement of satisfactoryresults because it is difficult to achieve accuracy and requires moreskilled labor. Particularly in the parts being in contact of the twoclosing elements, in which there are fitted rubber or plastic packings,tightness is not at all guaranteed, because they do not regularlyposition themselves in the wing part. In the central packings even aslight difference in the projection is such as to prevent the hermeticclosing of the fixture; in the structural shape types in which the glassinsertion takes place from the upper part, there occurs theinconvenience caused by the scarcely easy adjustment of the closingshutter, because it is not possible to center the fixture by means ofthe glass. In some structural shape types the glass fastening element isinserted from the wing side where the glass is resting, thus provokinginconveniences among which the impossibility of working at 45 anglesbecause of the fastening from the wing side, the drawback of notensuring an adequate final aesthetic appearance of the fixture, as wellas the difficulty of connecting the metallic structure with the fixture:also in the structural shapes in which there is provided the trip frontinsertion of the glass fastening element, there occurs the inconveniencethat the insertion is only possible on a surface in smooth condition andwith the aid of steel springs.

It is the specific object of this invention to provide an improvement inmetal structures of the type and applications stated or equivalent uses,and such as to ensure the elimination of all the above-outlined andother well known inconveniences. The invention resides in a determinednumber of elements which may be associated with each other in aplurality such as to develop the full range of fixtures, such as doors,windows, single or double, rolling and dumping both horizontally andvertically to movable walls, windows, kiosks, glasshouses forargicultural purposes, industrial type fixtures and other similarapplications: the aforesaid structural shape elements ensure with theaid of some simple complementary elements to accomplish other originalapplications. It is possible e.g. by the use of two appropriateelementsto build a double glass window and with more shutters with thepossibilty of inserting an insect-proof net or a third glass sheet;whilst with the use of one single element, it'is possible to build awindow, eliminating the application of related glass fastener. Thefixtures prepared with the use of the aforementioned elements ensure ahermetic seal, thereby avoiding the projections of the shutters from thefixtures.

Said advantageous industrial results are attained ac cording to thepresent invention, substantially because the improvement according tothis invention consists in developing a range of metal elements which ingeneral are obtained by extrusion. The characteristic basic structure isassociated with other structures relative to which it is placed in aposition, so that the resulting elements offer the possibility of beingused individually or in a plurality with the aid of simple cooperatingelements. In this manner all the parts are fitted together in a simpleand perfect manner.

These and further more specific features of the improvement according tothis invention will be better understood from the following detaileddescription of a preferred but non-limiting embodiment form of theinvention taken in conjunction with the accompanying drawings, in which:

FIG. 23 represents a complementary structure, utilizable as carillon,latch or the like, for the closing of shutters, windows and the like.

Referring now particularly to the Figures on the drawings, the improvedmetal structure according to this invention includes in its assembly abasic structural shape FIG. 1 which, suitably adapted in some cases,associates with other particular shapes so as to build other elements,which, when combined with each other, and, in turn, combined withcomplementary elements, ensure the preparation of any type of fixturerequired by the field applications; such basic structural shape, whichwill be shortly called A, is constituted, viewed in cross-section, of arectilinear section 30 to which an extension piece 31, is connectedfirst sideways and then perpendicularly. There is provided a seat 32,being prefarably of a trapezoidal configuration, and having a lateralhole, 64 adapted to receive a packing or gasket; the other end of thesection 30 is crossed by a perpendicular section 33 and the ends 34 and35 of which are constituted of a short section folded inward and ablock, 65 designed to provide the support for the glass the head ofwhich is resting against the small angle 36 integral with the section 30in the middle of which, but on the side opposite the latter there isprovided a U-shaped seat 37, designed to serve as a support for otherelements.

The basic shape A associates with a section 38 in the middle of whichthere is formed inwardly a clamp 39, adapted to serve as support for theglass FIG. 2 building an element B: a third element C FIG. 3 isconstituted of two type A basic shapes associated with each otheroverturned so as to form a T-shaped configuration or the like, and afourth element D FIG. 4 is likely consituted of two type A shapes, butoverturned and reversed in the mutual position so as to form a structurelike a Z, said resulting element being utilizable as an intermediateelement; a fifth element E FIG. 5 is constituted of a structural shapebeing generally of a quadrangular configuration 40, provided at the twoangles of one of the larger sides with two seats 41-42 and utilizablefor basements, whereas a sixth element F FIGS. 6 and 26 is consituted oftwo type A structural shapes associated with each other in an overturnedmanner and made integral by two shapes 43 and 43' so as to build aquadrangular body, utilizable for continuous facades. A seventh elementG FIG. 7 is constituted of the type A basic shape associated with twoother shaped parts 44 and 45 in order to form a clamp shape, utilizablefor controlling the sliding motion of latches and the like, whereas aneight element H FIG. 8 is constituted of the usual modified type A basicstructure, associated with two shaped sections 46-47 so as to build ahollow body, particularly utilizable in the restrained parts and thelike: a ninth element I FIG. 9 is finally constituted of two type Abasic structures arranged perpendicularly connected to each other by ashaped section 48 and two rectilinear section 49-50 disposed at rightangle to each other so as to form an element utilizable for thedelimitation of angles and the like. The aforementioned structures, usedindividually or in association with each other for the preparation offixtures of any type whatsoever are helped in some of such applicationsby a series of complementary elements characterized as follows: twostructural shapes 51 FIG. 10 and 52 FIG. 11, respectively, being of aC-shaped configuration, provided with short side extension pieces andutilizable as single glass fastener and double glass fastener, in thatsaid extension pieces are fitted with an end tooth 51 and 52,respectively, adapted to ensure the trip from insertion of the plate andwhich are introduced either in the seats which in the other difi'erentlyused elements serve to accomodate the tight seals or in the seats formedby the tooth 36; a quadrangular shape 53, provided with a C-shapedexpansion on one of the shorter sides and a quadrangular extension piecewith seat to receive the packing on one of the larger sides FIG. 12 tobe used as glass holding means; an angular shape 54 FIG. 13 provided atone end with a square-shaped extension piece and pointed at the otherend, utilizable for the junction of any structural shape of quadrangularconfiguration. Manifestly it is of universal application, in that byadapting it to the dimensions of the flange and the point, it permits toavoid the movement of the two coupled sections; as a matter of fact, byplacing the point of the shape at the bisectrix of the angle of thejunction and by associating this with another similar specimen placed at90 relative thereto, via the threaded means 55 FIG. 21 it is possible toobtain the self-centering of the structural shapes themselves inrelation to the sections to be joined which in this manner are locked.The threaded means 56, which may be screwed on the secured square,preferably from the low to the high of the shutter, permit the balancingof the glass, inasmuch as the latter may be raised as much as necessaryby screwing the aforesaid threaded means which is resting on its face.The series of the complementary elements is completed by: a structuralshape 57 FIG. 14 having a T-shaped configuration with shaped stem andprovided on an inner side of the cross-section with a tooth 57' andutilizable for the application of the movable wall fastener; astructural shape 58 FIG. 15 having a C-shaped configuration, providedwith shaped side and inner extension pieces as well as a short extensionpiece 58 for insertion purposes and utilizable for the completion of thefixture, and comprising a seat to accommodate the packing; two hinges 59and 60 FIGS. 16 and 17 of suitable angular shape and shaped theinsertion of which in the spaces arranged in the various elements isprovided with the consequent locking without the aid of subsidiarymeans, but simply by chiselling. The rods of the hinges are providedwith suitable channels 59'-59" and 60'-60", respectively. Thechisellings carried out on the walls of the seats grip to the channels;two elements 61 and 62, respectively, of a quadrangular configurationand provided with a side extension piece 61' and 61", respectively, aswell as a recessed seat 61" and 62", respectively, are utilizable on thesliding or openable shutters, thus avoiding the use of glass fasteners,because they may be directly inserted in said seat: the aforesaid twoelements FIGS. 24 and 25 are utilizable also in conjunction with theelement E in order to obtain the central cross-section or the socle ofwindow or balcony shutters, which may be closed with the use of thestructural shape 63 having an L-shaped configuration FIG. 23 which isslidably inserted in the hollow spaces provided, acting as seats formedby the other elements.

The improved structure according to this invention has been describedand represented by way of nonlimiting example and for demonstrating itsmain features, it being understood that, without departing from thescope of the invention, further changes and modifications as well asadditional improvements could be introduced therein.
